Gorgeous Cool Days Before a Wet Memorial Day Weekend

Wow, East Tennessee, it’s absolutely gorgeous out there today!
On this Friday, May 23, 2025, at 8:24 AM EDT, we’re basking in below-average temperatures that feel crisp and refreshing, a perfect springtime treat. From the vibrant streets of Knoxville to the serene trails of the Great Smoky Mountains and the rugged Cumberland Plateau, today’s clear skies and cool air invite everyone to soak up the beauty before a wetter pattern arrives for Memorial Day weekend. The EastTNweather platform, led by meteorologist Mike Witcher, delivers hyper-local updates via its app, website, YouTube, Roku, and Amazon Fire to keep you prepared.

Friday: Crisp, Cool, and Simply Gorgeous
Friday dawns with clear skies and chilly morning temperatures in the 40s and 50s across East Tennessee, a refreshing start that feels invigorating. As the day progresses, winds will pick up slightly, though less intense than Thursday’s gusts, with breezes reaching 10-15 mph. The air remains dry, with dew points in the 40s, keeping conditions comfortable as afternoon highs climb to the 60s and low 70s. This below-average weather is a springtime gem, perfect for enjoying the outdoors in Knoxville, Chattanooga, or the Smoky Mountains.

The EastTNweather app is your companion for planning today’s activities, offering real-time updates to track breezes or morning chill. Head out for a hike in Cades Cove, a picnic at Knoxville’s Tyson Park, or a stroll along Chattanooga’s riverfront, with the app’s hyper-local forecasts ensuring you stay comfortable. The dry, crisp air makes evening outings, like dining in Pigeon Forge or exploring Jonesborough’s historic charm, feel delightful. Dress in layers for cooler mornings, and seize this gorgeous day before the weather shifts.

Saturday: A Dry Start, Light Rain Arrives Through The Day
Saturday begins dry with a mix of sun and clouds, with morning temperatures in the 50s and highs reaching the low to mid-70s. Clouds will increase through the day as a weak wave approaches, bringing light rain mainly south of I-40 (Chattanooga, Cleveland, Athens) and along the Cumberland Plateau by evening. Rainfall amounts will likely stay below 0.25 inches, posing minimal disruption. North of I-40, including Knoxville and Morristown, expect mostly dry conditions with partly cloudy skies.

The EastTNweather platform’s streaming updates on YouTube, Roku, Amazon Fire, and Apple TV, led by Mike Witcher, provide context for Saturday’s forecast, while the app’s radar tracks light rain. Plan morning outings like festivals in Sevierville or hikes in the Smoky Mountains, with an umbrella handy for southern areas by evening. The app’s precision helps you time activities, ensuring you enjoy the dry start before clouds and light showers arrive. Saturday’s mild weather offers a final calm day before the wetter pattern takes hold.

Memorial Day Weekend: Wet Weather Dominates
A wetter weather pattern begins late Sunday and continues through Wednesday, with Memorial Day Monday looking particularly soggy. An area of low pressure will traverse Tennessee, bringing showers and storms, with rainfall totals of 1-2.5 inches expected over the next seven days, heaviest south of I-40 in Chattanooga, Cleveland, and Athens. Sunday starts with increasing clouds and afternoon showers, escalating into Monday’s widespread rain and possible thunderstorms. Tuesday and Wednesday will see off-and-on showers, with muggy dew points in the upper 60s fueling the wet conditions. Highs will hover in the low to mid-70s throughout.

The EastTNweather app’s alerts are essential for tracking this wet stretch, especially for Memorial Day plans in Knoxville, the Smoky Mountains, or Chattanooga. Indoor backups, like the East Tennessee History Center, the Tennessee Aquarium, or Dollywood’s indoor attractions, are critical, particularly south of I-40 where rain will be heaviest. The platform’s streaming updates on YouTube and Roku will refine the holiday forecast, helping you find dry windows for outdoor barbecues or hikes in Gatlinburg. Use the app’s radar to monitor storm tracks, and prepare for potential road ponding or minor flooding in saturated southern areas.

Wednesday and Beyond: Lingering Showers
The wet pattern lingers into Wednesday, with scattered showers and storms continuing, though coverage may decrease slightly. Highs will remain in the low 70s, with humid air keeping conditions sticky. South of I-40, expect the brunt of the rain, while northern areas like Knoxville and Morristown may see more breaks. The EastTNweather platform’s long-range forecasts will clarify the week’s end, with the app’s alerts ensuring you stay ahead of showers. Plan flexible activities, such as visiting the Knoxville Zoo during dry spells or exploring indoor venues in Chattanooga, using the app to time your outings.

The platform’s streaming updates provide a broader outlook, helping you prepare for commutes or outdoor events in the Cumberland Plateau. The lingering showers reflect East Tennessee’s active spring climate, where adaptability is key. As the wet pattern winds down, the app’s precision keeps your plans on track, ensuring you make the most of any sunny moments before the next system arrives.
